HONG KONG (AFP) - Brandon Rios believes Filipino great Manny Pacquiao will draw inspiration in the wake of Super Typhoon Haiyan, but that won't stop him trying to send the eight-weight world champion into retirement.

Rios sent his condolences after the giant storm slammed into the Philippines, leaving about 4,000 people dead and three million homeless, but said will have little sympathy for his opponent once they step in the ring for the World Boxing Organisation (WBO) welterweight title fight at the Venetian Macau resort on Sunday.

Pacquaio's trainer Freddie Roach said last week that he would have no hesitation in telling Pacquiao, who turns 35 next month, to quit if he suffered a third straight defeat in his "must-win" battle against Rios in Macau.

The "PacMan" has been one of the best pound-for-pound boxers of his generation, winning 10 world titles at eight different weights.

But the Filipino's legacy suffered in 2012 with his first defeats in seven years: a controversial points loss to Timothy Bradley, and a devastating sixth-round knockout to Juan Manuel Marquez last December.

The 27-year-old Rios has no doubt he will make it three in a row and force the man with a record of 54 wins, five defeats and two draws, in a pro career spanning almost 19 years, to hang up his gloves for good.

"I'm young, I'm hungry and I want it. I want the success," said the nine-year pro with a record of 31 wins and just one defeat, on points to Mike Alvarado in their junior welterweight rematch in March.

"Pacquiao has done great. No one can say he didn't because he won world titles at eight weights. But it's time he should call it quits. It's time for me," added the former World Boxing Association (WBA) lightweight champion.

"I want to beat the best to be the best and to be recognised as one of the best. And so that's why I'm going to win."
